I sold some of the percentage of Bitcoin to invest in Ethereum and I can see the loss I made from the investment. I invested in Ethereum when the price was $3,658 and that is about 4 month now and till now the price has not reached $3,400 and I have sold 20% of the investment as lost price. Jumping from one coin to another is very dangerous. You can lost everything in the process.
And now ETH has hit 3,700 dollars. This means you have made a small profit if you still hold it. Maybe this is not a big profit because you bought it at $3,658. But this proves that if you have a conviction and you use cold money then you can still make a profit in crypto.
Jumping from one project to another is very risky. I prefer to stay in one project but it is a project with good fundamentals because I like to hold coins for the long term.
